Wow, what a pathetic wanker. I mean, I know that tertiary education is more flexible about things (on a number of occasions I've eaten breakfast or lunch in classes and lectures, but I study design, and we're allowed to be pretty relaxed as long as we're still productive, and coffee breaks during classes are very productive) but if it's made clear something's a no-no in classes or lectures because your university or department has decided it's a distraction, them's the breaks. Live with it, it's higher education, not a fucking democracy.
